* Test release 2.10.1.
* acspecific.m4 (AC_PROG_CC_WORKS, AC_PROG_CXX_WORKS): New macros
adapted from Jim Meyering and automake.
(AC_PROG_CC, AC_PROG_CXX): Use them.
* acgeneral.m4 (AC_TRY_RUN_NATIVE): Split out of AC_TRY_RUN.
(AC_TRY_LINK): Check that the executable exists after linking.
(AC_EGREP_CPP): Disable m4 quote chars around egrep, so [] in regexps
isn't eaten.
* autoheader.sh: Add multiple-inclusion protection for config.h.
* acgeneral.m4 (AC_PREFIX_PROGRAM): Pretty up the output.
(AC_CHECK_LIB): Include the function being tested in the message.
(AC_CHECK_PROG, AC_PATH_PROG): Add a dummy variable to force word
splitting on the path.
* acspecific.m4 (AC_FUNC_MMAP): Remove check and uses of valloc.
It turns out it's a separate issue, for GNU grep.
Replace the test program with a new version from Mike Haertel.
* acgeneral.m4 (AC_CACHE_SAVE): Accept the HP-UX sh 'set' output
format. From Marcus Daniels <marcus@sysc.pdx.edu>.
* acgeneral.m4 (AC_MSG_CHECKING, AC_CHECKING): Write a message to
config.log also. From "T.E.Dickey" <dickey@clark.net>.
(AC_CHECK_LIB, AC_CHECK_HEADER, AC_CHECK_HEADERS): Replace use of
tr with sed, to avoid a bug in the AIX 4.1.3.0 tr reported by
Alain KNAFF <Alain.Knaff@imag.fr>. He says that version of
tr interprets \055 magically like an unquoted -.
* acspecific.m4 (AC_PROG_MAKE_SET, AC_CHECK_HEADER_DIRENT,
AC_CHECK_HEADERS_DIRENT): Ditto.
* acspecific.m4 (AC_FUNC_SETPGRP): New macro.
* acconfig.h (SETPGRP_VOID): New entry.
From "T.E.Dickey" <dickey@clark.net>.
* acspecific.m4 (AC_PATH_X_DIRECT): Try /lib/usr/lib/X11 for A/UX.
From Guillermo Gomez <gomez@mi.uni-erlangen.de>.
(AC_PATH_XTRA): Replace -R with LD_RUN_PATH in the
Solaris kludge. From Paul Eggert <eggert@twinsun.com>.
(AC_PATH_XTRA): Replace -R with adding LD_RUN_PATH to CC in the
Solaris kludge. Suggested by Paul Eggert <eggert@twinsun.com>.
Define X_DISPLAY_MISSING with AC_DEFINE, and
if not using X, clear out the X variables.
Check system-dependent libs before system-independent ones.
Check for more system-dependent libs.
From Karl Berry.
Use AC_CHECK_FUNC in the system-dependent libs tests.
From Larry Schwimmer <rosebud@cyclone.stanford.edu>.
Wart removal: Don't require AC_ISC_POSIX.
(AC_ISC_POSIX): Don't blather about being called before AC_TRY_LINK,
which is now called in AC_PROG_CC. Don't encourage using this macro.
* acconfig.h (X_DISPLAY_MISSING): Add entry.

From "Glenn P. Davis" <davis@unidata.ucar.edu>.
Don't require the second char after the type name to be a space.
(AC_TRY_RUN): Remove the test files before executing the "failure"
case code.

Look into quoting of cache variable values reported by Paul Eggert.

configure-time pasting together of output files from multiple pieces.

I wonder if it is possible to get the path for X11's app-defaults

Here is a matrix of mmap possibilities:
mmap private not fixed
mmap private fixed at somewhere currently unmapped
mmap private fixed at somewhere already mapped
mmap shared not fixed
mmap shared fixed at somewhere currently unmapped
mmap shared fixed at somewhere already mapped
For private mappings, we should verify that changes cannot be read()
back from the file, nor mmap's back from the file at a different
address. (There have been systems where private was not correctly
implemented like the infamous i386 svr4.0, and systems where the
VM page cache was not coherent with the filesystem buffer cache
like early versions of FreeBSD and possibly contemporary NetBSD.)
For shared mappings, we should conversely verify that changes get
propogated back to all the places they're supposed to be.
Grep wants private fixed already mapped.
The main things grep needs to know about mmap are:
* does it exist and is it safe to write into the mmap'd area
* how to use it (BSD variants) */

/* Thanks to Mike Haertel and Jim Avera for this test.
Here is a matrix of mmap possibilities:
mmap private not fixed
mmap private fixed at somewhere currently unmapped
mmap private fixed at somewhere already mapped
mmap shared not fixed
mmap shared fixed at somewhere currently unmapped
mmap shared fixed at somewhere already mapped
For private mappings, we should verify that changes cannot be read()
back from the file, nor mmap's back from the file at a different
address. (There have been systems where private was not correctly
implemented like the infamous i386 svr4.0, and systems where the
VM page cache was not coherent with the filesystem buffer cache
like early versions of FreeBSD and possibly contemporary NetBSD.)
For shared mappings, we should conversely verify that changes get
propogated back to all the places they're supposed to be.
Grep wants private fixed already mapped.
The main things grep needs to know about mmap are:
* does it exist and is it safe to write into the mmap'd area
* how to use it (BSD variants) */
